diskonaut VS btdu

Have been using ncdu for more than a decade, and recently started using diskonaut for similar purposes. Was looking for a terminal-based treemap visualization for analyzing disk usage and stumbled upon diskonaut, which is exactly that.

My favorite tool for this is diskonaut -- it's quicker than repeatedly running du and pleasant to use.

For a visual person like me, diskonaut is especially useful. It draws the space in rectangles on the screen that you can navigate into. If you resize the terminal it redraws the boxes.

A lot of unix-y tools have been rewritten in rust, where the usefulness comes from it being faster or having more features. Examples: bat, cw, lsd, ripgrep, diskonaut, gping. Maybe you could find an interesting program to rewrite?

While I usually use ncdu, diskonaut's output is closer to baobab. https://github.com/imsnif/diskonaut

Hello. I have a 2 TB nvme mounted as a subvol that contains dockervols. I recently noticed this discrepancy df -h | grep nvme0n1p1 /dev/nvme0n1p1 1.9T 1.3T 569G 70% /data vs. sudo du -h -d 0 /data 1.1T /data I tried using the btdu tool but I am not sure if I had it installed correctly as it didn't show the output like the examples shown on the github (https://github.com/CyberShadow/btdu)

btdu fastest and easiest tool to analyze space usage in compressed btrfs with lots of snapshots (especially in expert mode)

It doesn't seem BTRFS's fault. You could run btdu on your subvolumes to understand what's going on.

However, honestly, the best way to get a quick overview of where all your space is being used is btdu.

If you want to diagnose where you think there may be space used up that you don't quite understand, then btrfs fi du and third party tools btdu and compsize are useful.

And btdu to get an overall impressions of where space is being used if the above isn't useful enough.
